c# 直连solidworks 简单实现

纯用python写solidworks二次开发太痛苦了，重新回顾几年前写的c#

using System; using System.IO; using System.Runtime.InteropServices; using SolidWorks.Interop.sldworks; using SolidWorks.Interop.swconst; namespace SwDxfExporter { class Program { static void Main(string[] args) { try { // 替代 Marshal.GetActiveObject var progId = "SldWorks.Application"; Type comType = Type.GetTypeFromProgID(progId); object comObject = Activator.CreateInstance(comType); SldWorks swApp = (SldWorks)comObject; // 后续逻辑不变... ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc; if (swModel == null || swModel.GetType() != (int)swDocumentTypes_e.swDocPART) { Console.WriteLine("错误：请打开一个 SolidWorks 零件文档 (.sldprt)。"); return; } string fullPath = swModel.GetPathName(); if (string.IsNullOrEmpty(fullPath)) { Console.WriteLine("错误：文档尚未保存，请先保存文件。"); return; } string directory = Path.GetDirectoryName(fullPath); Console.WriteLine($"成功！文档所在目录:\n{directory}"); } catch (Exception ex) { Console.WriteLine($"发生错误: {ex.Message}"); Console.WriteLine("提示：请确保 SolidWorks 正在运行。"); } Console.WriteLine("\n按任意键退出..."); Console.ReadKey(); } } }
